Repairs And Upgrades On My Burke #4

Mark, I went down to my shop and did a quick measurement of the center to center distance its about 4 ⅜ inches
I'll measure the slot in the morning and I'll also get a measurement with calipers in the morn.
Thanks for the info on the cast iron.

Mark,
I went to my garage and I took the head off the Burke and I disassembled it so I could get the best possible measurements.
I made a template of cardboard with some of the measurements, I have also included some more photos of the base separated and
laid out for you to glee some more info before you start cutting the cast iron.
#1 The center to center measurement from the 2" TOP hole to the center of the LOWER hole is 4.316 measured from the template very close to 4 3/8
#2 The distance from the center of the LOWER hole to the center of the slot is 1.780.
I am not sure if all these back plates are the same as its a pretty good chunk of cast iron some of the measurements may be off a little, If I may
suggest it may benefit you to make a drawing or template based on the photos and sizes i have given you here to be sure it all lines up before
you start cutting. If you are interested in the template I made I can mail it to you. Let me know
I can't seem to upload photos every one i try I get ERROR uploading your file. look below they finally posted. alot of the photos would help a lot.

Wally,

I had trouble with photos for a while. I found, I was taking them with my phone and that was the problem. I found when I take a photo, I have to edit it. I crop it just a little bit and save it. Then my photos load correctly. If you are using your phone to take photos, try cropping a little bit , then save. Then upload the photos.

Thank you for the dimensions. I think the photos would help a lot. If you can't load them here , can you email them , maybe?

my email is. markfrazier16137@yahoo.com
 
Wally,

Thank you for the photos and in formation. Armed with this, I think I can duplicate the plate.
 
Mark, Just a last try at upload for the photos, I'll be damned not one single error.

Now that I have all the needed information , I am starting the cast iron mounting plate for my vertical head. I have to check and double check as I can't afford to screw up this $86 hunk of cast iron. First I set it up in the band saw to cut it to size.

I laid out the holes, but need a way to bore them. I don't have a boring head and besides there is no room to use a boring head on the Burke. I took a small 3" four jaw check and converted it into a boring head.

While the little chuck converted to a boring head works great, I found it did not have enough travel to bore the larger hole. So..... I resurrected a failed boring head project from about a year and a half ago that really went bad. After about 4 hours of drilling, milling, turning, and reaming, the failed mess started to look pretty good. I got the pancake boring head completed and works great. ( it is a pancake boring head because it is much shorter than a standard boring head, which is a necessity for a Burke mill)

The cast iron plate for my vertical head is coming along nicely. I'm boring the holes now. I found the distance between them to be 4.250"
